I for one started out wondering how I would read through all the terms and conditions and manage to get 5 credits for the 10K promo. However, it's been a lot easier than I thought it would be and I will have even more than five.
Please keep this thread pure (i.e. no flames please)... and share what you've already done to get the five credits. I thought it might be helpful for those who haven't yet finished, and interesting for those who have.
Personally, I think the most ingenious credits are those earned without spending a dime.
Here's mine:
1. Sprint Long Distance
2. Clickmiles Transfer to NW (Feb.)
3. Shop4.com purchase
4. Clickmiles Transfer to SPG (then to NW)
5. Clickmiles Transfer to NW (Mar.)
In addition, I've sent two recent hotel stays to NW to cover myself and even purchased some really cheap stuff at PlanetRx for the extra ClickRewards miles.
Good luck all! (And thanks for being on the boards wp!)
